These peanut butter cups turned out quite cute, if I may say so. These are the cupcake liners Aunt Laurie sent in our Christmas tin this year, and I love them so much. She had filled the tin with kitchen-related things in this (my favorite) shade of green, and after I trimmed a little off the tops of these papers, they were the perfect depth for peanut butter cups. If I were giving these as a gift, I'd double the liners/papers so the chocolate and no-stick spray wouldn't shine through and discolor them the way they did in places here, but this is the first time I'd used wrappers/made them as cups instead of just shaping them into chocolate-covered peanut butter items (Easter eggs, Valentine hearts, etc.), so live and learn.
The first time I made these, I used a slightly different recipe and shaped them into footballs for a Super Bowl party, piping lacing onto their tops.
It was more fun this time with the cupcake wrappers since it's the papers' folds that give them the brand-name peanut butter cup look. The recipe I used for these is based on this "Top Secret" one. I made a few changes based on the comments and past experience: I used the all-natural (oil-on-the-top) reduced-fat peanut butter, I added an extra pinch of salt, I used close to a cup of powdered sugar, I sprayed the cupcake liners, and I only waited maybe ten minutes after the chocolate base/side layer had cooled before adding the flattened-out ball of the peanut butter mixture to it (and maybe another ten after spooning the chocolate top layer over the peanut butter ball/middle). These set up really fast. It was cold the night I made this batch, so I just let the cups chill beside an open window instead of bothering with the fridge or freezer. This will probably be another Christmas tradition for us now, so it's nice that it's an easy and inexpensive (only four ingredients) recipe.
Mike's the peanut butter-lover in this household, and he thinks these are just like the brand name peanut butter cups--"or better"--so there you go. I promise not to poke your belly if you eat too many. ;)
